Introduction

VSC8514XMK-14 is a powerful interface ASIC designed to provide an optimized physical layer solution for Fibre Channel applications. It enables switch and router vendors to build high-performance systems with low power consumption, while allowing the use of existing components and tools to minimize design complexity. This article outlines the application field and working principle of the VSC8514XMK-14.

Application Field and Working Principle

Application Field

The VSC8514XMK-14 is primarily used in Fibre Channel applications, such as storage systems, routers, switches and network interface cards. It is a robust, reliable solution that is well-suited for higher-end, higher-throughput solutions requiring a wide range of configurable data paths and communications.

Working Principle

The VSC8514XMK-14 utilizes a set of programmable data rate converters and multiplexers to connect different interfaces in a Fibre Channel system. The user has the ability to program the rate of the physical connection, allowing for data transmission over different link protocols such as 10 Gbps, 8 Gbps, 4 Gbps, 2 Gbps, and 1 Gbps. The multiplexers allow for multiple simultaneous transmission links over the same physical link. This capability makes the VSC8514XMK-14 well-suited for applications requiring high-speed links.

The VSC8514XMK-14 also features an integrated 10-bit scrambler and descrambling module. The scrambler helps to regulate data packet transmission in order to prevent data bursts which can lead to deadlocks or congestion in data communication networks. The descrambling module provides an efficient mechanism to decode and restore the transmitted data back to its original form.

The VSC8514XMK-14 also includes an integrated Laser Driver Module which provides the user with an easy-to-use interface for controlling the laser transmit power levels. The module provides a number of features such as an adjustable output level, an adjustable pulse width, an adjustable rise and fall time, and an adjustable offset for the laser source. All of these features can be easily configured and adjusted to meet the needs of a specific system.

Conclusion

The VSC8514XMK-14 is an effective physical layer solution for Fibre Channel applications. It offers an integrated 10-bit scrambler, an integrated Laser Driver Module, and programmable data rate converters and multiplexers, which allow for high-speed data transmission across multiple links. As a result, this powerful interface ASIC is a reliable and robust solution for designing systems requiring a wide range of configurable data paths and communications.
